E46 CSL Race Airbox
Product description
The Karbonius BMW M3 E46 CSL Race Airbox has been developed specifically for BMW S54 engines, offering one of the most advanced and exclusive carbon intake solutions available for this model.
Manufactured entirely from pre-impregnated carbon fiber (prepreg) and cured in an aluminium mould and autoclave oven, it guarantees exceptional structural quality and surface finish. All parts are produced at our facilities in A Coruña (Spain) under ISO 9001 quality standards and by highly qualified personnel.
Its design incorporates an integrated curved snorkel, optimised to channel fresh air from the front of the vehicle, minimising the intake of hot air from the engine bay and improving the efficiency of the intake system.
In addition to improving engine performance, this intake delivers the distinctive, spectacular sound of S54 engines with a carbon airbox, complemented by a high-gloss UV-protected finish that enhances the look of the engine bay.
All units are individually numbered and include their corresponding certificate of authenticity, guaranteeing their origin and exclusivity.
